DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of an evaluation support device, an evaluation support method, and an evaluation support program will be described below with reference to Figures 1 to 15. In this embodiment, the evaluation support device, the evaluation support method, and the evaluation support program will be described as being used when evaluating the ground of a site on which a building is to be constructed. As shown in FIG. 1, an evaluation support system A1 of this embodiment includes an evaluation support device 10 and a modeling device 20 connected to each other via a network.

[0010] (Hardware configuration description) 2, the hardware configuration of the information processing device H10 that constitutes the evaluation support device 10 and the modeling device 20 will be described. The information processing device H10 includes a communication device H11, an input device H12, a display device H13, a storage device H14, and a processor H15. Note that this hardware configuration is an example, and it can also be realized by other hardware.

[0011] The communication device H11 is an interface that establishes a communication path with other devices and executes data transmission and reception, and is, for example, a network interface or a wireless interface.

[0012] The input device H12 is a device that accepts input of various information, such as a mouse, a keyboard, etc. The display device H13 is a display or the like that displays various information. The storage device H14 is a storage device that stores data and various programs for executing various functions of the evaluation support device 10 and the modeling device 20. Examples of the storage device H14 include a ROM, a RAM, and a hard disk.

[0013] The processor H15 uses programs and data stored in the storage device H14 to control each process in the evaluation support device 10 and the modeling device 20. Examples of the processor H15 include a CPU and an MPU. The processor H15 loads programs stored in a ROM or the like into a RAM and executes various processes for each process.

[0014] The processor H15 is not limited to a processor that performs all of its processing using software. For example, the processor H15 may include a dedicated hardware circuit (e.g., an application-specific integrated circuit (ASIC)) that performs hardware processing for at least some of the processing it performs. That is, the processor H15 may be configured with the following:

[0015] [1] One or more processors that operate according to a computer program (software). [2] One or more dedicated hardware circuits that perform at least some of the various processes [3] Circuits containing combinations of these The processor includes a CPU and memory, such as RAM and ROM, that stores program code or instructions configured to cause the CPU to perform processes. Memory, or computer-readable media, includes any available media that can be accessed by a general-purpose or special-purpose computer.

[0016] (Each function of the evaluation support system A1) Next, each function of the evaluation support system A1 will be described with reference to FIG. The evaluation support device 10 is a computer system that executes processing to support the management of ground information. Various information is input using this evaluation support device 10. Then, a three-dimensional model is displayed using a viewer. This evaluation support device 10 includes a control unit 11 and an input sheet storage unit 12.

[0017] The control unit 11 performs the processes described below (processes including an acquisition stage, a conversion stage, a display stage, etc.). By executing a processing program for this purpose, the control unit 11 functions as a support processing unit 111, an interface unit 112, a viewer unit 113, etc.

[0018] The support processing unit 111 supports the input of information into the modeling device 20. In this embodiment, each sheet of a spreadsheet file is used to acquire information to be input into the modeling device 20. The support processing unit 111 stores data related to thresholds for the difference between the measured and predicted depths of the strata and thresholds for the gradients of the strata in order to evaluate the strata boundary surfaces. These thresholds can be set arbitrarily by the user.

[0019] The interface unit 112 converts the information entered on each sheet of the spreadsheet file into a format (data format) that can be input to the modeling device 20 . The viewer unit 113 outputs a screen for viewing the three-dimensional model generated by the modeling device 20.

[0020] As shown in FIG. 3, the input sheet storage unit 12 stores a spreadsheet file 120 created using a spreadsheet application program. This spreadsheet file 120 is recorded when a spreadsheet file entered by a person in charge is acquired. This spreadsheet file is composed of multiple sheets, each containing an input field for various information. The spreadsheet file 120 includes a survey location sheet 121, a stratum classification name sheet 122, a ground surface survey sheet 123, a columnar diagram sheet 124, a cross-sectional diagram sheet 125, a pile sheet 126, and an earth retaining wall sheet 127. The columnar diagram sheet 124 to the earth retaining wall sheet 127 can each contain multiple sheets. Each sheet is entered using the drawings in the construction plan R1, the expected cross-sectional diagram in the ground investigation report R2, and the boring log R3.

[0021] As shown in FIG. 4(a), the survey position sheet 121 records data on the model name, the model lower limit elevation, the model creation range, the number of grid divisions, the plan view image file name, and the like.

[0022] The model name is the name of the ground model to be generated. The model lower limit elevation is the lower limit of the elevation at which the three-dimensional model is placed. The model creation range is a coordinate system that specifies the range of the ground model to be placed in three-dimensional space. In this embodiment, the model creation range is set by the lower left X coordinate (m), the lower left Y coordinate (m), the upper right X coordinate (m), and the upper right Y coordinate (m).

[0023] The number of grid divisions is the number of divisions in the X and Y directions. This determines the length of each side of one grid that makes up the model creation range and the aspect ratio. The floor plan image file name is the name of the file of the structural design floor plan of the building to be placed on this site. By using this floor plan image file name, the structural design floor plan can be obtained.

[0024] As shown in FIG. 4(b), the stratum classification name sheet 122 records data on the stratum ID, stratum division, color, attributes, etc. for each stratum classification. The stratum ID is an identifier for identifying each stratum. The stratum classification is a symbol that indicates the soil type of the stratum. For example, "B" indicates a fill layer, "OSG" indicates a sandy / gravel layer, "OC" indicates a clayey soil layer, etc., and a number indicating the layer is added to the symbol. The color is the color scheme used to display this layer. The attribute is an attribute such as the type of the stratum (for example, topographic surface, deposition, etc.).

[0025] As shown in FIG. 4(c), data relating to altitude and the like is recorded for each coordinate on the ground surface survey sheet 123. The coordinates are the coordinates of a position measured on the earth's surface. The elevation is the elevation of this location.

[0026] As shown in Figure 4(d), stratum information is recorded for each borehole used in the boring survey on the log sheet 124. This stratum information includes data on the borehole ID, hole mouth elevation, borehole location coordinates, minimum depth, soil type, stratum ID, stratum type, standard penetration test results, etc. The minimum depth, soil type, stratum ID, stratum type, and standard penetration test results are recorded for each stratum in this borehole.

[0027] The borehole ID is an identifier for identifying each borehole for geological survey. The hole mouth elevation is the elevation of the drilling hole opening position. The boring position coordinates are the planar coordinates (X, Y) on the plan where the boring was performed.

[0028] The minimum depth is the depth of the bottom of the stratum. A stratum consists of the area from the minimum depth of the upper stratum to this minimum depth. Soil type is a classification of soil type. For example, fill, silty fine sand with gravel, fine medium sand with gravel and silt, silty clay, sand with gravel, silty clay, silty fine sand, silt, sand and gravel with clay, silty clay, clayey sand and gravel, fine sand, sandy silt, etc. are recorded.

[0029] The stratum ID is an identifier that identifies the stratum that contains this soil type. The stratum classification is the stratum classification corresponding to this stratum. This stratum classification is set in accordance with the stratum classification name sheet 122. The standard penetration test results for this soil type are recorded, including the starting depth, penetration amount, number of hits, and N-value.

[0030] As shown in FIG. 4(e), data relating to a section line ID, section line coordinates, etc. for identifying a desired section are recorded on the section view sheet 125.

[0031] The section line ID is an identifier for identifying each section. The cross section line coordinates are the plane coordinates (X, Y) on the plan view where the multiple nodes that make up the cross section are placed. The cross section of the vertical plane in the depth direction is formed by using the line segment that connects the cross section line coordinates of each node associated with one cross section line ID in order as the upper side.

[0032] As shown in FIG. 4(f), the pile sheet 126 records data related to the pile ID, coordinates, pile diameter, pile top height, pile length, and the like. The stake ID is an identifier for identifying each stake. The coordinates are the plane coordinates (X, Y) on the plan where the piles are to be placed.

[0033] The pile diameter is the diameter of the pile. The pile top height is the elevation of the pile head. The pile length is the length of this pile.

[0034] As shown in FIG. 4(g), data relating to the retaining wall ID, coordinates, top height, length, etc. are recorded on the retaining wall sheet 127.

[0035] The retaining wall ID is an identifier for identifying each retaining wall. The coordinates are the plane coordinates (X, Y) on the plan where this retaining wall will be placed. The top elevation is the elevation of the top of this retaining wall. The length is the depth of this retaining wall.

[0036] 1 is a computer system that executes a process for generating a three-dimensional model of ground information. The modeling device 20 includes a modeling unit 21 and a model information storage unit 22.

[0037] The modeling unit 21 performs a modeling process (3D CAD process) using 3D CAD (computer-aided design) technology to represent each element related to the ground as a 3D model (object) and place it in a 3D virtual space. This modeling can manage not only the shape of the element but also the attributes (properties) of the element. For example, attribute information (e.g., geological classification information) of each element is stored.

[0038] The model information storage unit 22 records three-dimensional model information created using the modeling unit 21. This three-dimensional model information is recorded when a three-dimensional model is generated using the modeling unit 21. The three-dimensional model information includes three-dimensional model information (object ID, element model, placement information, attribute information) for each model name.

[0039] The model name information is the name of the ground model to be generated. The object ID is information about an identifier for identifying the three-dimensional shape (three-dimensional model) that constitutes the stratum.

[0040] The element model is information about a three-dimensional object (three-dimensional model) that constitutes a stratum, etc. In this embodiment, a stratum estimation model, a boring model, a pile model, and an earth retaining wall model are used as elements.

[0041] The placement information includes information about the placement of the three-dimensional model (coordinates in the three-dimensional virtual space). The attribute information includes the contents of each element model. The attribute information of the stratum estimation model records information such as the stratum classification name sheet 122 and the log sheet 124. The borehole object records the borehole ID and the like from the log sheet 124. The pile object records the pile ID and the like from the pile sheet 126. The retaining wall object records the retaining wall ID and the like from the retaining wall sheet 127.

[0042] (Support processing) The support process will be described with reference to FIGS. As shown in FIG. 5, the control unit 11 of the evaluation support device 10 executes an input process for the range to be modeled (step S01). Specifically, first, a spreadsheet application program is started. Then, the support processing unit 111 of the control unit 11 outputs a template spreadsheet file 120 to the display device H13. This spreadsheet file 120 is provided with an investigation position sheet 121 to an earth retaining wall sheet 127, and each item is left blank. In this case, the model name, model lower limit elevation, model creation range, number of grid divisions, and plan view image file name are input in the investigation position sheet 121. In this case, the support processing unit 111 of the control unit 11 records the spreadsheet file 120 in the input sheet storage unit 12.

[0043] 6, a model creation range 510 is set by referring to a floor plan 500 corresponding to the structural design floor plan specified by the floor plan image file name on the survey position sheet 121. In the modeling device 20, this model creation range 510 is divided into the specified number of grid divisions.

[0044] Next, the control unit 11 of the evaluation support device 10 executes a process for inputting stratum type information (step S02). Specifically, the control unit 11 inputs the stratum ID, stratum classification, color, attributes, etc. for each stratum classification in the current ground into the stratum classification name sheet 122. In this case, the support processing unit 111 of the control unit 11 updates the stratum classification name sheet 122 of the spreadsheet file 120 recorded in the input sheet storage unit 12.

[0045] Next, the control unit 11 of the evaluation support device 10 executes a process for inputting borehole information (step S03). Specifically, information regarding the borehole ID, hole mouth elevation, position coordinates, minimum depth, soil classification, stratum ID, standard penetration test results, etc. is input for each borehole in the log sheet 124. In this case, the support processing unit 111 of the control unit 11 sets the stratum classification corresponding to the input stratum ID from the stratum classification name sheet 122 in the log sheet 124. Then, the support processing unit 111 updates the log sheet 124 of the spreadsheet file 120 recorded in the input sheet storage unit 12.

[0046] Next, the control unit 11 of the evaluation support device 10 executes an input process of the cross-section line coordinates (step S04). Specifically, information on the cross-section line ID, cross-section coordinates, etc. for confirming the desired cross-section is input into the cross-section sheet 125. In this case, the support processing unit 111 of the control unit 11 updates the cross-section sheet 125 of the spreadsheet file 120 recorded in the input sheet storage unit 12.

[0047] For example, as shown in Fig. 6, for one section line ID, section coordinates c1, c2, and c3 are set in order for multiple nodes in the plan view 500. Also, for another section line ID, section coordinates c4, c5, and c6 are set in order for multiple nodes.

[0048] Next, the control unit 11 of the evaluation support device 10 executes input processing for pile information and earth retaining wall information (step S05). Specifically, information regarding the pile ID, pile diameter, pile top height, pile length, coordinates, etc. is input into the pile sheet 126. Also, information regarding the earth retaining wall ID, coordinates, top height, length, etc. is input into the earth retaining wall sheet 127. In this case, the support processing unit 111 of the control unit 11 updates the pile sheet 126 and the earth retaining wall sheet 127 of the spreadsheet file 120 recorded in the input sheet storage unit 12.

[0049] Next, the control unit 11 of the evaluation support device 10 executes a conversion process (step S06). Specifically, the interface unit 112 of the control unit 11 converts the information of each sheet of the spreadsheet file 120 recorded in the input sheet storage unit 12 into a format compatible with the modeling device 20. Then, the interface unit 112 inputs the converted various pieces of information into the modeling device 20.

[0050] Next, the modeling device 20 executes a process for generating a stratum model (step S07). In this case, the modeling unit 21 generates a 3D model of each stratum based on the information acquired from the interface unit 112. Specifically, first, the modeling unit 21 generates a cylindrical 3D model for each borehole position coordinate. Next, the modeling unit 21 arranges the stratum using the minimum depth of each stratum relative to the borehole position coordinate. Next, the modeling unit 21 estimates stratum boundary surfaces in the adjacent surrounding cylindrical 3D models so as to connect common stratums. In this case, the stratum surfaces are smoothed using an approximation method. Then, the modeling unit 21 records a 3D model (stratum estimation model) in which the estimated stratum boundary surfaces are set in the model information storage unit 22. Furthermore, the modeling unit 21 generates pile models and earth retaining wall models based on the information recorded on the pile sheet 126 and earth retaining wall sheet 127, and records them in the model information storage unit 22.

[0051] Next, the control unit 11 of the evaluation support device 10 executes a process of outputting the three-dimensional model (step S08). Specifically, the viewer unit 113 of the control unit 11 acquires the geological formation estimation model recorded in the model information storage unit 22. Then, the viewer unit 113 outputs the display screen 600 to the display device H13.

[0052] In this case, as shown in Fig. 7, a stratum estimation model 601 for each stratum is output in a three-dimensional virtual space on a display screen 600. Also, cross-sectional lines 602 and 603 are displayed on the ground surface. The cross-sectional line 602 is specified by cross-sectional coordinates c1, c2, and c3. The cross-sectional line 603 is specified by cross-sectional coordinates c4, c5, and c6.

[0053] When a cross-section display is instructed, the viewer unit 113 instructs creation of a cross-section using the geological formation estimation model recorded in the model information storage unit 22. 8, the viewer unit 113 acquires a display screen 610 including a cross-sectional view from the modeling device 20. Cross sections 612 and 613 corresponding to the cross-sectional lines 602 and 603 in the geological formation estimation model are displayed on the display screen 610.

[0054] When a command to display the supporting layer is issued, the viewer unit 113 identifies a supporting layer whose N value exceeds a reference value in the stratum estimation model recorded in the model information storage unit 22. The user may specify a stratum to be regarded as the supporting layer. In this case, the viewer unit 113 identifies the specified stratum as the supporting layer. 9, the viewer unit 113 acquires a display screen 620 including the support layer, the boring, and the piles from the modeling device 20. This display screen 620 includes a support layer model 621, a boring model 622, and a pile model 623.

[0055] When an instruction to display the retaining wall is given, the viewer unit 113 generates the retaining wall model recorded in the model information storage unit 22. 10, the viewer unit 113 acquires a display screen 630 including the retaining wall from the modeling device 20. This display screen 630 includes a retaining wall model 631.

[0056] Next, the control unit 11 of the evaluation support device 10 executes a process for displaying a cross-sectional view (step S09). Specifically, the support processing unit 111 of the control unit 11 outputs a cross-sectional view selection screen. On this cross-sectional view selection screen, multiple borehole IDs are specified. In this case, the support processing unit 111 generates a cross-section whose upper side is a straight line connecting the coordinates of each borehole position. Then, the support processing unit 111 outputs a cross-sectional view obtained by cutting out the geological formation estimation model at the generated cross-section.

[0057] 11, when a cross-sectional display is instructed, a display screen 640 is output. This display screen 620 displays a cross-sectional view of the strata corresponding to boring positions 641 to 645. In addition, the standard penetration test results (N value) are displayed at each of the boring positions 641 to 645.

[0058] Next, the control unit 11 of the evaluation support device 10 executes a process for checking the stratum boundary surface (step S10). Specifically, the support processing unit 111 of the control unit 11 acquires the lower limit depth for each stratum recorded on the log sheet 124 for each borehole position coordinate. In this case, as shown in FIG. 12, an actual measurement table 651 is generated in which the minimum depth is recorded for each boring position coordinate and for each stratum.

[0059] Next, the support processing unit 111 calculates the estimated lower limit depth of the stratum at the borehole position coordinates in the stratum estimation model recorded in the model information storage unit 22. In this case, as shown in Fig. 12, an estimation table 652 is generated in which the estimated lower limit depth is recorded for each borehole position coordinate and for each stratum.

[0060] Then, the support processing unit 111 calculates the difference between the minimum depth in the actual measurement table 651 and the estimated minimum depth in the estimation table 652 for each stratum at each borehole position coordinate. If the difference exceeds the elevation difference threshold, the support processing unit 111 outputs a warning message. This warning message includes information that can identify the borehole position coordinate and the stratum.

[0061] Furthermore, the support processing unit 111 calculates the gradient in the depth direction in the shape of the stratum boundary surface of the three-dimensional model recorded in the model information storage unit 22. As shown in FIG. 13, a stratum boundary surface 66L is estimated at the boring position coordinates 661 to 666 according to the depth of the common stratum ST1. Note that in FIG. 13, the stratum boundary surface 66L is displayed as a line, but in three-dimensional space it becomes a two-dimensional surface. Next, the support processing unit 111 calculates the gradient SL1 at each position of the stratum boundary surface 66L. If the calculated gradient exceeds a gradient threshold (e.g., 60 degrees), the support processing unit 111 outputs a warning message about the gradient of this stratum. The warning message includes information that can identify the stratum and area that exceeds the gradient threshold.

[0062] Next, the control unit 11 of the evaluation support device 10 executes pile length evaluation processing (step S11). Specifically, the viewer unit 113 of the control unit 11 identifies the upper and lower sides of the support layer in the pile model. Then, the viewer unit 113 generates a display screen that allows the upper and lower sides of the support layer to be distinguished.

[0063] As shown in FIG. 14, when a pile display command is issued, a display screen 670 is output. On this display screen 670, a pile model 671 is displayed in three-dimensional space. In this case, the pile model 671 is displayed with the upper side p1 and lower side p2 of the supporting layer displayed in different colors. It is also possible for the user to create a stratum consisting of two layers, the supporting layer and the layer above it. In this case, the upper side p1 and lower side p2 of the supporting layer are displayed in different colors using a function for displaying the color of the layer that intersects with the pile.

[0064] Furthermore, as shown in FIG. 15, when a pile length adjustment display is instructed, a display screen 680 is output. This display screen 680 also displays a pile model 681 in three-dimensional space. In this case, the upper side p1 and lower side p3 of the support layer are displayed in different colors in the pile model 681. Here, the lower side p3 is adjusted to a predetermined length within the support layer. That is, if the pile does not reach the support layer, the pile length is increased so that it reaches the predetermined length within the support layer. On the other hand, if the pile is too deep below the support layer, the pile length is decreased so that it reaches the predetermined length within the support layer. As a result, the sum of the length of the upper side p1 and the length of the lower side p3 becomes the pile length required for each pile model 681. Note that the user may check the display screen 670 and re-input the length of the lower side p3 of the support layer.

[0065] According to this embodiment, the following effects can be obtained. (1) In this embodiment, the spreadsheet file 120 includes a survey location sheet 121, a stratum classification name sheet 122, a ground surface survey sheet 123, a columnar diagram sheet 124, a cross-sectional diagram sheet 125, a pile sheet 126, and an earth retaining wall sheet 127. By setting values ​​in the spreadsheet file, it is possible to set data to be handed over to the modeling device 20 that generates a three-dimensional model.

[0066] (2) In this embodiment, the control unit 11 of the evaluation support device 10 executes a conversion process (step S06), thereby converting the data in the spreadsheet file into a data format that can be used in the modeling device 20.

[0067] (3) In this embodiment, the modeling device 20 executes a process for generating a geological layer model (step S07), thereby generating a planar geological layer model using information on the discrete borehole logs.

[0068] (4) In this embodiment, the control unit 11 of the evaluation support device 10 executes a process for outputting a three-dimensional model (step S08). This allows the ground condition to be grasped in three-dimensional form. Furthermore, by using the viewer, the three-dimensional form can be efficiently confirmed without directly operating the modeling device 20.

[0069] (5) In this embodiment, the control unit 11 of the evaluation support device 10 executes a process for displaying a cross-sectional view (step S09), thereby enabling confirmation of the geological cross-section at a desired position. (6) In this embodiment, the control unit 11 of the evaluation support device 10 executes a confirmation process for the stratum boundary surface (step S10). This allows the validity of the stratum estimation model to be confirmed. Here, the support processing unit 111 outputs a warning message if the difference exceeds the elevation difference threshold. This allows the discrepancy between the estimated stratum depth and the actual measured value to be confirmed. Furthermore, if the calculated gradient exceeds a gradient threshold (e.g., 60 degrees), the support processing unit 111 outputs a warning message about the gradient of this stratum. This allows the stratum with an unusual shape to be confirmed.

[0070] (7) In this embodiment, the control unit 11 of the evaluation support device 10 executes pile length evaluation processing (step S11), thereby making it possible to calculate an accurate pile length according to the position of the supporting layer.

[0071] This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility. In the above embodiment, the evaluation support device 10 and the modeling device 20 are used, but the hardware configuration is not limited to this. For example, the evaluation support device 10 and the modeling device 20 may be configured as an integrated device.

[0072] In the above embodiment, the control unit 11 of the evaluation support device 10 executes the input process of the stratum type information (step S02). Alternatively, the stratum ID, stratum classification, color, attributes, etc. may be set in advance for each general-purpose stratum classification in the stratum classification name sheet 122.

[0073] In the above embodiment, the control unit 11 of the evaluation support device 10 executes a boring information input process (step S03). Here, a log sheet 124 is used, on which information related to the borehole log R3 of the ground investigation report R2 is set. Here, when the control unit 11 of the evaluation support device 10 acquires the borehole log R3 of the ground investigation report R2, the control unit 11 may identify the borehole log R3 by image recognition and set the character-recognized information on the log sheet 124.

[0074] In the above embodiment, the control unit 11 of the evaluation support device 10 executes input processing of pile information and earth retaining wall information (step S05). However, as long as it is an underground structure, it is not limited to piles and earth retaining walls.

[0075] In the above embodiment, the control unit 11 of the evaluation support device 10 executes a process for checking the stratum boundary surface (step S10). Here, the support processing unit 111 outputs a warning message if the difference exceeds the elevation difference threshold. In this case, the area in the stratum estimation model where the difference exceeds the elevation difference threshold may be highlighted.

[0076] Furthermore, if the calculated gradient exceeds a gradient threshold (e.g., 60 degrees), the support processing unit 111 outputs a warning message about the gradient of the stratum. In this case, the area in the stratum estimation model where the calculated gradient exceeds the gradient threshold may be highlighted.
